MOUNTING FOR. OIL-BURNERS.

To all whom t may concern.'

Be it known that I, LENA E. JARVIs, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented certain new and useful Improvements in Mountings for Oil- Burners, of which the following is a -speciication.

This invention relates to improvements in rotary spray burners for liquid fuel such as hydrocarbon oils, and more particularly to that type of burner set forth in Patent No. 1,201,828, granted to me October 17, 1916.

vThe invention has for its principal object to provide an oil burner adapted for suspending on a furnace door or .wall plate and which is capable of swingingv relatively thereto to admit of accessibility to the tip thereof; to provide an improved swinging joint mounting for the burner and associated parts whereby contact is made for supplyingl current to the motor when the burner is `flush with the furnace door and the contact is automatically broken on the removal or swin ing of the burner from the door; to provi e a hinge construction enabling the fuel to be carried through the same and the excess fuel returned to the source of supply thereby eliminatingr numerous pipe joints and connections.

With the above mentioned and other objects in view, the invention consists in the n ovel construction and combination of parts hereinafter described, illustrated in the accompanying drawings and pointed out in the' claim hereto appended; it being understood that various changes inthe form, proportion, size, and minor details of construction within the scope of the claim may vbe resorted to without departing from the spirit or sacrificing any of the advantages of the invention. l,

To more fully comprehend the invention, reference is directed tovtheraccompanying drawings wherein Figure 1 is a view 1n perspective of the preferred embodiment'of my improved-ap-v paratus, illustrating the burner swungaway from the furnace door or wall plate.

Fig. 2 is an enlarged side elevation of my improved apparatus, illustrating the arrangement of the difl'erentparts thereof.

. Referring more particularly 4 to the several views of the drawings, wherein like characters of reference designate corresponding parts,-l indicates a suitable platform or .base secured at ,one end to therear wall 2 of a fan or blower casing, said platform mountmg on its opposite end a motor 3. The wall 2 is provided with a central air inlet 4in the center of which is positioned a bearing support 5 carried by a web 6. An outlet 7 is provided centrally of the front case wall 8 and over the same is fitted a cup or housing 9. An auxiliary air inlet chamber 10 secured to the front of the fan casing has its front wall 11 provided with an outwardly projecting cone 12 surrounding the cup or housing in spaced relation. This auxiliary air is admitted to promote combustion.

Extending through the bearing support 5 and carried by a bearing 13 is a rotatable shaft 14 carrying on its outer end the cup 15 'disposed Within the cup or housing 9, with its ,outer wall in spaced relation to the inner wall of said housing providing a space for the normal air for proper combustion of the fuel.

support 17'.|` A suitable fan 20is mounted on the shaft 14 within the-fan or blower casing, and is so designed that on the rotation of the shaft 14 the same will draw air through the inlet 4 and force the same under pressure around the cup- 15, confining the ame in cup formation. ,The shaft 14 extends rearwardly through a transmission gear housing 21 and connects with a motor armature shaft 22 through the coupling 23.

.Thus it will be apparent that the operation of the motor will rotate the shaft 14, which in turn operates the cup `15 and fan 20.

`Extending fromthe housing 21 is a' shaft 24 having geared connection with thet shaft 14 and said shaft cooperates through a coupling 25 with a suitable fuel pump of any well-known type in a casing 26.

Extending from the side wall 11 of the chamber 10 are the hinged butts 27 adapted to lie between coperating hinge butts extending outwardly from the face of the furnace door or wall plate 29 secured in any suitable manner to the furnace proper (not shown), and provided with the burner receiving opening 29. Passing through the coperating hinge butts are suitable hinge pins in the form of pipes 30 and 31, provided at their upper ends with the respective swinging joints 32 and 33, said pipe 30 below its joint 32 being connected to a fuel feed pipe 34 leading to a fuel supply not shown. The pipe 30 above the joint 32 egtends to the pump casing 26, and the Vil .pumped under pressure from said casing passes through the pipe 35 to the cup 15; the pipe passing upwardly in the fan or blower case in advance of the fan 2O and terminating in a goose neck 36 within said cup shaped support 17. A control valve 37 is mounted within the pipe 35 and leading from said pipe intermediate said valve and the pump casing 26 is-a pressure relief pipe 38 in which is mounted a relief valve 439', and said pipe communicates with the pipe 31; the excess fluid returning to the supply source (not shown) through the pipe 40.

Surrounding the pipe 38 above the upper coperating hinge members is an electric con# tact member comprising the disks 41 and 42 of 'insulating material received in an inverted cup or protecting member 43, said members being provided in their centers with alined openings through which said pipe 38 extends.

The disk 4l is held stationary within the pipe 38. by the key or pin 44, and the same carries the contacts y45 with which are connected the leads 46 passing through a conduit 47 in thecover 43 and leading to a suitable source of power. The disk 42 carries contacts 48 from which extend the leads 49 surrounded by the conduit 50 secured at one end to the disk and extending to the motor to which it is secured asat 51, and with which said leads connect. rlhe contacts 45 and 48 are so arranged as to coperate when the platform or base is swungto a position as in Figs 2 and 3, at which time current is supplied to operate the motor. A. suitable spring 52 coiled about the pipe 38 eX- erts pressure on the disk 41 and maintains the same in tight frictional contact with its operating disk 42.

It is apparent that thecon'structon of the contact members is such as to provide a neem/ef? switch for controlling the operation of the motor, as the disk 42 swings with the platform l, and when the platform is at right angles with the door 29 the contacts 45 and 65 48 are in register causinga How of current to the motor and permitting the motor to operate to rotate the burner cup, fan and fuel pump.

On the swinging of the burner away from 7@ the doors, as in Fig. l, the engagement between contacts 45 and 48 will be broken and current to the motor will be automatically interrupted, thereby stopping the feed of the. fuel to the fire, thus reducing the liability of the operator becoming burned.

If desirable, auxiliary air inlets 53 may be provided in the periphery of the chamber 10, and said inlets are preferably controlled by a damper 54 within said chamber, oper- 80 ated by a handle 55.

A. suitable pivotally mounted latch 56 carried by a member 57 on the door 29 is adapted to engage over the rear wall of the cham-v ber 1() and maintains the burner in closed 85 position, with the burner cup thereof exa tending through the door opening, as in Fig. 4 of the drawings.

By my impraved construction it will be y\ apparent that the fuel feed and pressure re^90\ turn pipesfrom the motor pass through and provide a hinge pin for mounting the burner and associated parts onto the furnace plate or door thus overcoming the numerous joints and pipe connections now ifniversally used a@ for this purpose.

Having thus described my invention, what l claim is An oil burner mounting including a furnace plate or door member provided with a ma. burner opening therein, a platform hinged to one side thereof to swing on a vertical axis and adapted for mounting the burner apparatus including the pump and motor units to enable the same to swing as a unit 1105/1` relative to the opening in said plate or door, a pair of pipes extending from a source of fuel supply and providing hinge pins for said hinge and on which said platform swings, said pipes adapted to carry fuel oil 11G to said burner apparatus and to permit the escape of excess fuel therefrom, and an electric motor control carried by said hinge for conveying current to the motor on said platform. y

ln testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
